Typically, the attacks are brought on by a failure to put security rules in place and to use easily available security tools Firewall, Intrusion Detection System, and Intrusion Prevention Systems are some of the security solutions that are accessible. Each tool comes with its own set of features. its characteristics, benefits, and drawbacks

Deep Neural Certificate less Hessian Heap Sign cryption for Secure Data Transmission in Wireless Network

Systematic and well grounded data transmission over wireless networks has been substance of uninterrupted research over the last few years. The paramount is scrutinizing the amount of security provisioning owing to the security challenges during transmission over wireless network. In fact, it is moderate to eavesdrop and alter data packets. Accessing the personal computer and public network possess the potentiality to apprehend the network traffic possibly compromising the privacy. Therefore for wireless applications, it is essential to ensure data integrity during data transmission. To efficiently address the above issues, a Deep Neural Certificate less Hessian Curve Heap Sign cryption (DNC-HCHS) method for secured data transmission in wireless network is proposed. Compared with the conventional, Certificate less Sign cryption DNC-HCHS method improves the data confidentiality and data integrity by generating smaller keys employing the Hessian Curve Heap function. Additionally with the assistance of the access point or the aggregator, the sensitivity of heaped sign crypted cipher text can improve the security of data transmission and reduce the message delivery time. Aimed at reducing the delay in data transmission, application of Certificate less Hessian Curve Heap Sign cryption in Deep Learning (i.e., Deep Neural Network) performs the overall process in a swift manner and performs a much better encryption. Simulation is performed to validate the viability and efficiency of the proposed method. The results show that the data confidentiality and data integrity rate are strongly improved, while the delay is minimized.

K-Banhatti Invariants Empowered Topological Investigation of Bridge Networks

Any number that can be uniquely determined by a graph is called graph invariants. During the most recent twenty years’ innumerable numerical graph invariants have been described and used for correlation analysis. In the fast and advanced environment of manufacturing of networks and other products which used different networks, no dependable assessment has been embraced to choose, how much these invariants are connected with a network graph or molecular graph. In this paper, it will talk about three distinct variations of bridge networks with great capability of expectation in the field of computer science, chemistry, physics, drug industry, informatics, and mathematics in setting with physical and synthetic constructions and networks, since K-Banhatti invariants are newly introduced and have various forecast characteristics for various variations of bridge graphs or networks. The review settled the topology of bridge graph/networks of three unique sorts with three types of K-Banhatti Indices. These concluded outcomes can be utilized for the modeling of interconnection networks of Personal computers (PC), networks like Local area network (LAN), Metropolitan area network (MAN) and Wide area network (WAN), the spine of internet and different networks/designs of PCs, power generation interconnection, bio-informatics and chemical structures.

BLE-Based Indoor Tracking System with Overlapping-Resistant IoT Solution for Tourism Applications.

In this paper, an overlapping-resistant Internet of Things (IoT) solution for a Bluetooth Low Energy (BLE)-based indoor tracking system (BLE-ITS) is presented. The BLE-ITS is a promising, inexpensive alternative to the well-known GPS. It can be used in human traffic analysis, such as indoor tourist facilities. Tourists or other customers are tagged by a unique MAC address assigned to a simple and energy-saving BLE beacon emitter. Their location is determined by a distributed and scalable network of popular Raspberry Pi microcomputers equipped with BLE and WiFi/Ethernet modules. Only simple triggered messages in the form of login records (LRs) are sent to a server, where the so-called path vectors (PVs) and interest profile (IPr) are set. The authors implemented the prototype and demonstrated its usefulness in a controlled environment. As it is shown in the paper, the solution is highly overlap-resistant and mitigates the so-called multilocation problem.

Improvement of accounting representation of non-current assets

The essence of non-current assets is investigated and their main components are revealed in this paper. The problems of accounting for non-current non-monetary assets, which currently occupy an important share in the total value of assets, are studied. The place of new types of property – computer programs, electronic databases, websites (online stores, electronic printed publications and other electronic media) in the structure of non-current assets in particular, and property of the enterprise in general is determined. It is proved that such property is be closely related to the application of computer equipment and computer networks such as the Internet. In order to summarize the selected features and characteristics of this type of property, it is proposed to combine them into the separate group called «Electronic Property». Allocated objects are neither things nor property rights, the amount of money invested in this property is huge, and the turnover from the sale of goods and services via the Internet (online stores) is significant. On the global scale, such manipulations make it possible to clarify the concept and meaning of the term «intangible assets». The concept of «electronic property» is defined as property that has no material, natural form, which functions exclusively in conjunction with the physical resources of personal computers or computer networks. In order to organize the accounting of the investigated type of property, it is proposed to combine it into a separate accounting group «electronic assets» and to use for reflection in the accounting system the following accounts of the Chart of Accounts: 128 sub-account – «electronic assets», 136 subaccount – «depreciation of electronic assets». The main stages of accounting for non-current assets: identification and definition of non-current assets; classification of non-current assets; evaluation of non-current assets for accounting purposes; criteria, norms, methods of depreciation; principles of objects depreciation impossibility; procedure (methodology) for accounting of non-current assets aiming to determine the financial result are identified.

Specimen Temperature Detection on a Clinical Laboratory Pre-Analytic Automation Track: Implications for Direct-from-Track Total Laboratory Automation (TLA) Systems.

Clinical laboratory regulations require temperature monitoring of facilities, reagent and specimen storage, as well as temperature-dependent equipment. Real-time specimen temperature detection has not yet been integrated into total laboratory automation (TLA) solutions. An infrared (IR) pyrometer was paired with a complementary metal oxide semiconductor (CMOS) laser sensor and connected to an embedded networked personal computer (PC) to create a modular temperature detection unit for closed, moving clinical laboratory specimens. Accuracy of the detector was assessed by comparing temperature measurements to those obtained from thermocouples connected to battery-operated data loggers. The temperature detector was then installed on a pre-analytic laboratory automation system to assess specimen temperature before and after processing on an integrated thawing and mixing (T/M) robotic workcell. The IR temperature detector was able to accurately record temperature of closed, moving specimens on a pre-analytic automation system. The effectiveness of the T/M workcell was independently verified using the temperature detector. Specimen reroute on the pre-analytic automation track was identified as a potential risk for frozen specimens being inadvertently delivered to future, connected instrumentation. Automated IR temperature detection can be used to verify specimen temperature prior to instrument loading and/or sampling. Such systems could be used to prevent frozen specimens from being inadvertently loaded onto analytical instrumentation in TLA solutions.

BLOCKCHAIN: AN ANALYSIS ON NEXT-GENERATION INTERNET

The blockchain is a peer to peer technology that protects the integrity of a digital piece of information. It can serve as a digital decentralized distributed ledger that can record sharing of information between two parties in a permanent way. All the information is stored in a network of personal computers. Each computer has memory records called blocks and each block has a time stamp and a link to the previous block as a hash pointer. All the records are secured using cryptography. Timestamp keeps the track of creation of the record. Once the record is created no one can manipulate the records, not even the owner. It keeps the proof and exact time at which that data exists. A hash function is a mathematical algorithm and algorithm is made is in such a way that is it a one-way function that means the process cannot be rolled back. Next generation of the Internet will be using in FITS.

Agent-Based Distributed Computing for Dynamic Networks

Dynamic networks of personal computers are characterized by sudden, unexpected failures of computational nodes, as well as the addition of new computers at any given moment. This paper presents a new agent-oriented system for distributed computing, named ADiS, specifically designed for operating in these kinds of environments. The system relies on the agent technology in order to adapt to dynamic changes in a computational net-work. Originally envisioned as a distributed system for distance matrix calculations, ADiS has recently been redesigned as a general-purpose, extensible architecture for arbitrary computing in a distributed environment. Experimental results demonstrate that the usage of ADiS has a significant positive impact onto the execution time of lengthy processes. DOI: http://dx.doi.org/10.5755/j01.itc.43.1.4588

Wolkite Smart City Community Cloud Computing with Cyber Security

Cloud Computing is development fast, with its data centers evolving at an extraordinary rate. However, this has come with worries over privacy, efficiency at the expense of flexibility, and environmental sustainability, because of the dependence on Cloud vendors such as Google, Amazon and Microsoft. Our answer is an alternative model for the Cloud conceptualization, providing a model for Clouds in the community, utilizing networked personal computers for liberation from the centralized vendor model. Community Cloud Computing (C3) offers an alternative architecture, created by combing the Cloud with models from Grid Computing, principles from Digital Ecosystems, and sustainability from Green Computing, while remaining true to the original vision of the Internet. It is more technically challenging than Cloud Computing, having to deal with distributed computing issues, including varied nodes, varying quality of service, and additional security constraints. However, these are not incredible challenges, and with the need to recall control over our digital lives and the potential environmental significances, it is a challenge we must follow.

Cyber security: challenges for society- literature review

security is the activity of protecting information and information systems (networks, computers, data bases, data centres and applications) with appropriate procedural and technological security measures. Firewalls, antivirus software, and other technological solutions for safeguarding personal data and computer networks are essential but not sufficient to ensure security. As our nation rapidly building its Cyber- Infrastructure, it is equally important that we educate our population to work properly with this infrastructure. Cyber-Ethics, Cyber-Safety, and Cyber-Security issues need to be integrated in the educational process beginning at an early age. counter measures help ensure the confidentiality, availability, and integrity of information systems by preventing or mitigating asset losses from security attacks. Recently cyber security has emerged as an established discipline for computer systems andinfrastructures with a focus on protection of valuable information stored on those systems fromadversaries who want to obtain, corrupt, damage, destroy or prohibit access to it. An Intrusion Detection System (IDS) is a program that analyses what happens or has happened during an execution and tries to find indications that the computer has been misused. A wide range of metaphors was considered, including those relating to: military and other types of conflict, biological, health care, markets, three-dimensional space, and physical asset protection. These in turn led to consideration of a variety of possible approaches for improving cyber security in the future. These approaches were labelled Heterogeneity ,Motivating Secure Behaviour and Cyber Wellness . plays an important role in the development of information technology as well as Internet services. Our attention is usually drawn on Cyber Security when we hear about Cyber Crimes. Our first thought on National Security therefore starts on how good is our infrastructure for handling Cyber Crimes. This paper focus on cyber security emerging trends while adopting new technologies such as mobile computing, cloud computing, e-commerce, and social networking. The paper also describes the challenges due to lack of coordination between agencies and the Critical IT Infrastructure.

Implementation of real-time distributed control for discrete event robotic systems using Petri nets

This article presents a systematic method of modeling and implementing real-time control for discrete-event robotic systems using Petri nets. Because, in complex robotic systems such as flexible manufacturing systems, the controllers are distributed according to their physical structure, it is desirable to realize real-time distributed control. In this article, the task specification of robotic processes is represented as a system control-level net. Then, based on the hierarchical approach, it is transformed into detailed subnets, which are decomposed and distributed into the local machine controllers. The implementation of real-time distributed control through communication between the system controller and the machine controllers on a microcomputer network is described for a sample robotic system. The proposed implementation method is sufficiently general, and can be used as an effective prototyping tool for consistent modeling, simulation, and real-time control of large and complex robotic systems.

Virtual Machines And Networks - Installation, Performance, Study, Advantages And Virtualization Options

The interest in virtualization has been growing rapidly in the IT industry because of inherent benefits like better resource utilization and ease of system manageability. The experimentation and use of virtualization as well as the simultaneous deployment of virtual software are increasingly getting popular and in use by educational institutions for research and teaching. This paper stresses on the potential advantages associated with virtualization and the use of virtual machines for scenarios, which cannot be easily implemented and/or studied in a traditional academic network environment, but need to be explored and experimented by students to meet the raising needs and knowledge-base demanded by the IT industry. In this context, we discuss various aspects of virtualization - starting from the working principle of virtual machines, installation procedure for a virtual guest operating system on a physical host operating system, virtualization options and a performance study measuring the throughput obtained on a network of virtual machines and physical host machines. In addition, the paper extensively evaluates the use of virtual machines and virtual networks in an academic environment and also specifically discusses sample projects on network security, which may not be feasible enough to be conducted in a physical network of personal computers; but could be conducted only using virtual machines.
